A: Rust Prevention Powder Guide for Steel Media in Vibratory Finishing

When using steel media as the grinding material in vibratory finishing, it is an ideal solution for high-precision deburring and polishing of metal workpieces. Rust prevention powder plays a critical role in wet finishing processes, effectively preventing corrosion while improving surface smoothness. Below is a professional guide to applying rust prevention powder for steel media finishing.

Core Functions of Rust Prevention Powder

• Anti-Oxidation: Prevents rust formation during wet finishing with water-based compounds, protecting steel, stainless steel, or aluminum components.

• Enhanced Polishing: Works synergistically with steel media to remove micro-burrs and oxide layers, achieving a mirror-like finish.

• Protection of Media and Workpieces: Minimizes direct impact between steel media and parts, reducing scratches and extending media lifespan.

Choosing the Right Rust Prevention Powder

• Aluminum Oxide (Alumina, #120–#800 grit): Suitable for coarse to medium finishing, effective for burr or oxide removal.

• Cerium Oxide Polishing Powder (0.5–2 µm): Best for fine polishing of stainless steel and aluminum alloys.

• Chemical Rust Inhibitors (with phosphates): Added to finishing liquid to provide long-term corrosion protection.

Key Usage Guidelines

• Media & Powder Pairing:

  • Coarse finishing: #120–#240 powder with 3–5 mm steel media.

  • Fine polishing: #800+ or ultra-fine powder with 1–2 mm media for high-gloss surfaces.

  • Avoid overly fine powders that may clog gaps and reduce efficiency.

• Compound Ratio:

  • Add 5–15 g of rust prevention powder per liter of finishing liquid.

  • Prefer neutral or mildly alkaline liquids to ensure chemical compatibility.

• Finishing Time:

  • Typically 1–6 hours, depending on workpiece size and finish requirements.

  • Regularly monitor concentration to maintain anti-rust effectiveness.

• Cleaning & Maintenance:

  • Rinse workpieces with clean water or use ultrasonic cleaning to remove residue.

  • Periodically clean the processing bowl to prevent dust buildup and maintain media performance.

• Safety Precautions:

  • Wear dust masks and protective goggles when handling powders.

  • Ensure proper ventilation to minimize dust hazards.

Vibratory Finishing Machine | High-Efficiency Surface Polishing & Deburring Equipment

A vibratory finishing machine is an advanced surface finishing solution designed to achieve polishing, deburring, edge rounding, descaling, and surface smoothing through high-frequency vibrations. By generating powerful vibratory force with an eccentric-weight motor, the machine drives workpieces, media, and compounds into a three-dimensional motion (up-and-down vibration, tumbling, and spiral circulation), ensuring consistent and high-quality finishing results.

Working Principle

1. Vibration Force Generation – The eccentric weight motor produces strong vibration force when activated.

2. 3D Motion – The specially designed vibratory bowl enables continuous spiral motion, including vertical vibration, tumbling, and rotational circulation.

3. Surface Processing – Workpieces, abrasive media, and finishing compounds rub against each other to achieve deburring, polishing, and edge rounding.

Key Features & Advantages

• High Efficiency – Significantly faster than traditional manual grinding and polishing.

• Automation & Cost Saving – Easy to operate, supports long-term automated processing, and reduces labor costs.

• Wide Applications – Suitable for metals, plastics, ceramics, gemstones, and resin components.

• Consistent Quality – Ensures uniform deburring, polishing, rust removal, and smooth surface finishing.

• Eco-Friendly – Dust-free operation, improving workplace safety and cleanliness.

• Ideal for Complex Shapes – Perfect for processing irregular, detailed, or hard-to-reach workpiece geometries.

Applications

• Metal Components – Stamping parts, die-castings, forgings for deburring, edge rounding, and polishing.

• Hardware Products – Electronic hardware, furniture hardware, and hand tools finishing.

• Jewelry & Gemstones – Polishing of gold, silver, jade, coral, and other precious materials.

• Plastics & Resins – Coarse grinding, fine finishing, and glossy surface polishing.

Hazards of Powder A Deposition

Causes of Powder Deposition during Grinding
Effect of Polishing or Grinding Fluids:

• Insufficient concentration or unstable chemical properties of polishing agents may prevent powder from effectively suspending in the grinding fluid, accelerating deposition.

• Some polishing agents may react with the powder, forming sticky precipitates.

Impact on Workpieces:

• Surface quality deterioration:
  Powder deposition on workpiece surfaces can cause scratches, dents, or uneven gloss, affecting appearance and functionality.
  Deposits may embed into the surface, especially in soft materials (e.g., aluminum, copper), making subsequent cleaning difficult.

• Dimensional accuracy affected:
  Powder accumulation may alter the grinding effect, resulting in dimensional deviations and impacting subsequent processing or assembly.

• Corrosion risk:
  If the powder contains metal debris and reacts with chemicals in the grinding fluid, localized surface corrosion may occur.

Impact on Machinery:

• Clogging of pipelines and filtration systems:
  Powder deposition may block grinding fluid circulation pipes or filters, reducing fluid flow and machine efficiency.
  Long-term blockage may cause pumps or motors to overheat, shortening machine lifespan.

• Reduced efficiency of grinding media:
  Powder adhering to grinding media surfaces can decrease cutting ability, affecting grinding efficiency.
  Deposits may alter the shape or surface characteristics of the media, leading to uneven grinding.

Solutions and Prevention of Powder Deposition

Optimize Grinding Fluids and Polishing Agents:

• Use polishing agents at appropriate concentrations to ensure good suspension and prevent rapid powder settlement.

• Select grinding fluids compatible with workpieces and media to minimize chemical reactions that form deposits.

• Regularly monitor fluid pH and concentration, replacing when necessary.

Select Appropriate Grinding Media:

• Choose media with suitable particle size according to workpiece material to avoid excessive fine powder generation.

• Regularly inspect media wear and replace worn-out media promptly.

Adjust Operational Parameters:

• Increase vibration frequency or grinding fluid flow rate to keep powder suspended and reduce deposition.

• Use staged grinding: start with coarse grinding to remove bulk material, then fine grinding with polishing agents to improve surface quality while minimizing powder accumulation.

Regular Cleaning and Maintenance:

• Thoroughly clean workpieces after each grinding session to prevent powder buildup.
